Year 3 Visit to RHS Harlow Carr Gardens
Sunday 7th May | 4 comments
What beautiful days! Two days in a row! Year 3 must have been working hard to earn two glorious days of sunshine!
The visit to RHS Harlow Carr Gardens began with a chance to explore the gardens in small groups. The children were amazed by the variety of flowers (big ones, small ones, colourful ones!) and enjoyed attempting to read the Latin names as well.
In class, children have learnt about the different parts of a plant and identified their functions. Having studied the roots, leaves and stem at school, a visit to the garden allowed them to begin looking at the function of the flower. After a stop for lunch, the children began their workshop on plant reproduction.
The workshop began with children identifying why plants are important:
- Plants provide oxygen through photosynthesis
- Plants provide food
- Plants can be used to build (wood from trees)
The children were also shown cotton plants and saw that even the clothes they wear were grown from the ground!
Afterwards, children learnt that the flower’s job is to attract pollinators (bees, butterflies, insects) so that flowers can pollinate. Bees, for instance, fly to one flower and ‘accidentally’ collect pollen on their bodies. When flying to a different flower of the same type, the pollen that has been collected rubs off against a different part of the flower. This then leads to the flower creating seeds which leads to more flowers.
OK. So that explanation didn’t include a lot of technical vocabulary. The children were shown a similar diagram to the one below to help identify different parts of the flower.
Children then explored the gardens to find the different parts of the flower. The children collected petals, carpels, stamen and sepals.
The petals are bright and colourful to attract pollinators.
The carpels are made up of the stigma (the very top), the style (the main stick) and the ovary (the very bottom). When a pollinator arrives at a plant with pollen in its fur, that pollen rubs against the stigma and travels down the style to the ovary where the plant can create seeds.
The stamen are made up of the anther (the very top, where pollen is kept) and the filament (the main stick). Pollinators, when eating nectar, rub against the pollen on the anther before flying off to a different plant where it might rub against the stigma.
The sepal protects the plant when it is first growing its flower. After the flower has grown, the sepal is no longer needed and dies.
Children were able to find all different parts of the flower around the gardens, collecting the parts and then labelling them back in the work room.
The children thoroughly enjoyed their visit to Harlow Carr and the staff were extremely impressed with their scientific knowledge and attitude throughout the day. Well done Year 3!
